Divide the diagram along the grid lines into some rectangles, so that each rectangle contains exactly one colored field. Actually each color corresponds to a number between 2 and 7 which indicates the area of the rectangle. Each grid cell must be part of one rectangle. For an example with numbers you may check the following address: http://wiki.logic-masters.de/index.php?title=Shikaku/en
Solution code: For each line the number of rectangles in this line, from top to bottom
